It is supposed to work if you are sure a previous running MS java process
is killed and the IP associated is still valid for the setup. A mac change
will cause CloudStack to think there is another MS node is UP, however, it
will try to detect if there is any other node which is currently using the
MS IP, it may do self-fencing to shut itself down if a previous running MS
java process is still running there.

The only requirement for it to work is that, mac address can be changed,
but the associated IP should be valid to the setup
